利用2017年1～12月当地降水资料和同期全球再分析资料,引入HYSPLIT和GrADS气象模型,定量分析金华地区大气降水的水汽输送特征。结果表明:(1)研究区逐月场降水的水汽来源、运移路径存在差异。逐月水汽变化过程与冬、夏季风具有密切的联系。其中,4～5月水汽输送呈现为冬、夏季风之间的转换特征;9～10月为夏、冬季风转型时期。(2)研究区水汽输送通道大致可分为四条:西太平洋、孟加拉湾-南海、欧亚大陆和局地水汽通道;另外,研究区不同高度层的水汽在冬、夏半年的水汽输送通道和贡献率不同。
In this paper, the characteristics of water vapor transport at different heights during the process of precipitating inJinhua area quantitatively were analyzed, by using the local precipitation data from January to December in 2017 and globalreanalysis at the same period. At the same time, the HYSPLIT trajectory model and GrADS weather model were introduced. Theresults of the study are as follows: (1) There are difference in the sources of water vapor and migration pathways at different timein the study area. The monthly water vapor change process is closely related to the winter and summer monsoons. In addition, thewater vapor transportation from April to May is characterized by the transition between winter and summer monsoons; fromSeptember to October, it is the transition period of summer and winter monsoons. (2) The water vapor channel in the study areacan be roughly divided into four categories: the West Pacific channel, Bengal Bay channel South China Sea channel, Eurasia andlocal channel. In addition, there is difference in water vapor transport channels and contribution rates at the various heights in thestudy area during the winter and summer.
